Gastric bypass surgery information
The first gastric bypass procedure was performed in 1994, and the method of performing this type of operation has developed over time with the emergence of new surgical technologies, to become safer and more effective compared to the older techniques used in the past. Gastric bypass is a great option when compared to the rest of weight loss procedures, as it results in more weight loss than adjustable gastric banding or gastric sleeve procedures do.
The advantage of this operation is that the weight loss it induces remains constant over time and the patient is less likely to regain weight after they have lost it.
Gastric bypass surgery definition
Gastric bypass surgery helps obesity patients lose weight by both restricting the amount of food a person consumes and reducing the total amount of calories absorbed by the gastrointestinal tract. Gastric bypass procedure also induces some hormonal and physiological changes when food doesn’t pass through the duodenum –first part of small bowel- , as it decreases ghrelin levels, which are the hunger hormone, and increases the levels of leptin hormone, which is the satiety hormone, thereby decreasing the feeling of hunger and suppressing appetite, restricting the amount of food the patient consumes
Types of Gastric bypass surgery
SASI is one of the most recent types of gastric bypass operations, and it has been called by this name because it is through which the path of food entering the stomach is divided into two tracks:
- The first track is the usual food route.
- The second food pathway is from the stomach to the end of the small intestine directly, bypassing a large portion of the bowel space.
Laparoscopic SASI bypass involves performing two simultaneous procedures, namely gastric sleeve, and gastric bypass, where the process is divided into two stages:
- The first stage: It is called (gastrectomy), in which approximately 80% of the stomach volume is cut, including the interior of the stomach.
- The second stage: It is called (gastric bypass) that takes place in conjunction with the first stage, in which a link or path is made between the stomach and the small intestine, resulting in determined and reduced food amount, which leads to a reduced amount of food absorbed from the body.
Gastric bypass surgery benefits
Gastric bypass surgery helps severe obesity patients to lose significant weight permanently, as the percentage of lost weight can reach about 60% of extra body weight within two years, in addition to this it helps patients improve the quality of their lives and their ability to do many activities.
Moreover, gastric bypass may treat or prevent several diseases, such as:
- Gastroesophageal reflux disease
- Heart disease
- High cholesterol
- Sleep and snoring disorders
- Type II diabetes mellitus
- Cerebrovascular accidents
